The 835 is a great turkey gun right out of the box. But the 870 is a better all round gun and you can add accessories over the years. You'd be happier in the long run with an 870.
That said, I love my 835 tho, but it is a dedicated turkey gun. I don't shoot anything else with it. It doesn't point well for wing shooting and the ported barrel would blow my duck hunting buddy's ear drums out! I have an 870 for all purpose use and they are better all round guns.
Happy Birthday!
